A. -20,-12,-8,-1,(1),5,10,x,x........ur other 2 numbers have to be greater then 1
B. x,-20,-12,-8,(-3),-1,1,5,10......ur other number has to be less then -3
Answer:
Step-by-step explanation:
- (y+9) = 10
Multiply through by -1 gives us
y+9 = -10
Subtract 9 from both sides
y = -19
That's your answer.
If you work it through it satisfies the equation.
That is:
- (-19 +9) = 10
-(-10) = 10
10 = 10
